The web contains an enormous amount of information, and Google has
helped to make that information more easily accessible by providing
pretty good search facilities. But not everything is written nor is
everything well organized to make it easily discoverable. There are
millions of people who possess useful knowledge that they would love to
share, and there are billions of people who can benefit from it. We
believe that many do not share that knowledge today simply because it
is not easy enough to do that. The challenge posed to us by Larry,
Sergey and Eric was to find a way to help people share their knowledge.
This is our main goal.
